Expanding generation capacity only way to avoid grid failures: Tata Power MD

The only option to avoid grid failures is to expand the generating capacity, according to Anil Sardana, Managing Director, Tata Power.

Tata Power is into generation, transmission and distribution.

“There needs to be enforcement of automated and coordinated relay system as also strict governance on frequency regimes to avoid grid failures similar to the one experienced over the last few days.

“However, one cannot shy away from creating spinning reserves by expanding India’s power generation capacities so that there is no demand-supply gap at any given time,” he said.

In parallel, the management of distribution companies has to be made accountable for 24x7 reliable supply and fiscal management, he felt.


On the recent power outages experienced across the country due to grid failures, he said Mumbai is a classic example of how this problem could be addressed technically thanks to the islanding scheme pioneered by Tata Power in 1981.

It cuts off the network from external grid failures to help the local network manage its power demand/ supply needs during such crisis. This islanding scheme has worked well for Mumbai consumers, achieving a 100 per cent success rate each of the 16 occasions that there have been such grid failures since 1995.

Even in the existing grid failures, Tata Power's Jojobera units islanded themselves with Jamshedpur load and continued operations.


“There cannot be a better trigger to set off reforms for the power sector to enable increased investment into generation to meet the country’s 12{+t}{+h} Plan target of 88,000 MW. The sector’s long sought-after need for reforms on fuel supply too needs to be addressed on an immediate basis. Clarity on Ultra Mega Power Projects (UMPPs) can go a long way in building a brighter future for the energy needs,” he said.

For instance, India’s first UMPP at Mundra (4000 MW), being set up by Tata Power, when fully operational, will meet about two per cent of the country’s energy needs.

The project will provide power to consumers in Maharashtra, Gujarat, Haryana, Punjab and Uttar Pradesh.

The first 800 MW-sized unit 1 has been commissioned and unit 2 has been synchronised. Units 3, 4 and 5 are on schedule.

INDIA SHOULD START MFGING FLOATING POWER PLANTS mounted on board the vessels or barges built in can be stationed near ports in water - seas - and can be tssransported wherever they needed quickly.TATAS- L&T,s should work on these projects with German-Japanese and European manufacturers.

Yes he is correct as on a number of occasions tata power network islanded from the grid & survive till the grid normalise. Government should address the problem of imported coal price as it's not economically possible for tata power to supply power at about Rs.2.30 per unit even though it had ppa with states. When RIL demanding gas price hike from KG basin, government should not ignore tata power's revision in tariff for mundra power as current international price of coal is too high. If discom sell this power for commerical user at about 7 RS , they should not allowed to do so because this kind of situation put our banks, financial institution under great stress when mundra power networh eroded in two to three years. Best solution is that this umpp power should be sell entirely to commerical & industrial consumer at much lower price which is beneficial for both b.s.

1. Capacity creation is a must 2. But the cost of electricity paid by consumer is 3 times more then what it should be.3. One unit of salable electricity need 700gms of coal. 4. Assuming average cost of coal @2700 PMT ( this is reasonable rate and will cover average cost of coal at present market prices) Cost of coal stands 190 paisa per unit 4.Add to it cost of capital and depreciation and wages in generation say 100 paisa now cost stands at 290 paisa 5. add 60 paisa as cost of distribution .. capital cost .. distribution cost now cost stands at 350 paisa per unit. 6. Allow 15pc of T&D loss in TD and in includes political distribution loss. Now the cost per unit stands at 404 Paisa per unit. 7. No SEB realizes , I repeat realizes on an average less then 500 paisa per unit. 8. Still no one is satisfied.
